Re: APOD: From Auriga to Orion (2021 Mar 22)

I took the image using H-alpha, SII and OIII filters and it's combined using the Hubble Palette. Very nice image. But I'm still confused: Wouldn't the Hubble Palette (Ha = green) make this picture much more green? Check out: http://bf-astro.com/hubblep.htm Yes I used a technique very similar to that.
